Wuxia Across the Heavens: I Collect Side Effects

After settling in, Su Xin immediately got to work.

He was well-prepared. He took out the flower spider eggs he had prepared from his bag and found a cool, damp corner in Butterfly Valley to carefully cultivate them.

These flower spiders were collected by him in his early years, originally intended for use in cultivating the Thousand Spider Poison Hand technique, and now they come in handy.

He never neglected his cultivation.

Every morning, he would meditate and cultivate in the open space he had cleared in the valley. First, he would use the Thousand Spider Poison Hand to circulate his internal energy, allowing the poison and internal energy to merge and flow in his meridians. Then, he would use the Vajra Subduing Demon Divine Power to repeatedly purify the internal energy mixed with poison, removing impurities so that his internal energy retained both the insidious poison of the Thousand Spider Poison Hand and the powerful and mellow strength of the Vajra Subduing Demon Divine Power.

As for the complete technique of the Thousand Spider Poison Hand, he had already handed it over to Hu Qingniu and Wang Nangu for study without reservation.

The couple had always been curious about this special poison technique, and now that they had obtained the complete manual, they treasured it even more, studying it every day, and even their usual bickering had decreased.

After all, those who can cultivate the Thousand Spider Poison Hand to the Thousand Spider Realm are extremely rare in the martial arts world, let alone the legendary Ten Thousand Poison Realm. Such a rare poison skill completely aroused the two people's desire to explore.

Besides the Thousand Spider Poison Hand and the Vajra Subduing Demon Divine Power, Su Xin did not slack off in his other martial arts skills.

He has been trying to integrate four special forces and combine the various martial arts he has learned to break through the bottleneck and form his own martial arts system.

Time flies, and half a year has passed in the blink of an eye.

On this day, in the open space of Butterfly Valley, Su Xin, dressed in a tight-fitting outfit, was concentrating on practicing his boxing techniques.

He stood tall and straight, and his punches and kicks carried a fierce and sharp aura. The wind from his punches whistled past, carrying a faint, sweet, and metallic scent.

That was a sign of the fusion of the internal force of the Thousand Spider Poison Hand and the Vajra Force.

Each punch is powerful and forceful, with eight different kinds of energy subtly surrounding the body. These energy types are either fierce, gentle, crisp, or long-lasting. They are the seven kinds of energy of the Seven Injury Fist, plus the Vajra energy of the Mighty Vajra Fist. The eight kinds of energy intertwine and entwine, without conflicting with each other, but rather complementing each other.

When the force of the punch dissipates, it will turn into a wisp of extremely fine black smoke. If you don't look closely, you will hardly notice it. That is the poisonous force of the Thousand Spider Poison Hand, which is hidden in the force of the punch and can hurt people silently.

As Su Xin finished practicing his fist technique, he paused slightly, then changed his fist into a finger, bringing his index and middle fingers together, gathering strength at the fingertips, and suddenly thrusting out.

The immense internal force and energy were compressed into an extremely fine finger wind, as sharp as a needle tip, and the sound of it cutting through the air could be clearly heard.

This finger technique contains both the powerful penetrating force of Vajra Force and the insidious corrosive power of the Thousand Spider Poison Hand, causing injury upon contact and eroding bones and destroying muscles.

"This move is called Steel Corrosion!" Su Xin stood up, his breath slightly ragged, but his eyes were full of joy.

The past six months of training have not been in vain. Not only has the Thousand Spider Poison Hand technique improved, but it has also successfully integrated Vajra Force, creating a new move that combines both power and venom.

Su Xin stood with his fingers retracted, the residual force in his fingertips not yet completely dissipated, but a trace of undisguised annoyance flashed between his brows.

After practicing the Corrosion Steel technique, he wanted to try to integrate the power of the Seven Injury Fist into his finger strength. However, the meridians in his fingers were too delicate. As soon as he exerted force, he felt a piercing pain and his fingertips went numb, as if they were about to break at any moment.

He frowned inwardly, muttering to himself:

The Seven Injury Fist's power is too fierce and complex; the meridians in the fingers simply cannot withstand it. Forcibly fusing it would probably ruin these hands.

What puzzled him even more was that the severe pain in his meridians caused by this forced cultivation had no effect on the side effects system in his body.

It seems that this system only recognizes martial arts techniques that come with inherent side effects from the original storyline, and it doesn't acknowledge the hidden dangers caused by haphazardly fusing and cultivating them on one's own.

Just as he was pondering the system's vulnerabilities, a burst of cheerful yet sharp laughter suddenly came from a room not far away. The laughter was extremely penetrating and instantly shattered the tranquility of Butterfly Valley.

The laughter was loud and unrestrained; it was obvious that it must have come from Wang Nangu.

The laughter grew closer, tinged with eagerness and smugness, as if some great joy had occurred.

Just as Su Xin came to his senses, a dark figure swept in front of him like a gust of wind. Before he could even steady himself, the laughter continued.

It was Wang Nangu, her face beaming with joy.

Wang Nangu's eyes gleamed, her face beaming with pride. She gestured with her chin towards Su Xin, her excitement barely concealed: "Haha! Su Xin, you've finally figured it out! I've got the method for breaking through the Thousand Spider Poison Hand you wanted!"

Before she finished speaking, she casually tossed a thread-bound notebook over, her movements swift and decisive.

Su Xin quickly reached out and caught it. Looking down, he saw that on the cover of the notebook, besides the five large characters "Thousand Spider Poison Hand", there were four smaller characters written below.

The five poisons are mixed together.

Upon seeing this, Su Xin was overjoyed. He didn't bother to think about the system anymore and quickly opened the notebook, focusing intently on reading it, afraid of missing any detail.

The notebook was filled with neat handwriting, densely packed with Wang Nangu's annotations and research notes, the core of which was the method to break through the Thousand Spider Poison Hand technique.

No longer limited to the toxicity of a single spider, but rather breaking out of the existing framework, we must delve into the heart of Miao territory or the summit of Kunlun Mountains to find five distinctly different highly venomous spiders.

These five types of spiders correspond to five types of deadly poisons: cold poison, fire poison, neurotoxin, bone-rotting poison, and hallucinogenic poison.

The method of cultivation involves simultaneously absorbing the toxins of these five spiders into the body, drawing upon Wang Nangu's lifelong research into the art of mixing poisons, and forcibly fusing these five highly toxic substances with contradictory and incompatible properties together.

The medium and adhesive that combines these five deadly poisons is the flower spider that Su Xin has been cultivating.

In her annotations, Wang Nangu wrote that she had discovered the key to how flower spiders could absorb a variety of toxins.

The venom of this spider has extremely strong compatibility, which is the core reason why the Thousand Spider Venomous Hand was able to break through to the Thousand Venomous Realm. She had never seen through it before.

It wasn't until Su Xin cultivated the spotted flower spider and carefully studied it that she understood the characteristics of its venom.

Looking at the contents of the notebook, Wang Nangu stood aside, her tone tinged with regret and envy: "Speaking of which, the Thousand Spider Poison Hand is truly a miraculous skill, perfectly blending internal energy with poison techniques. If it weren't for the disfiguring side effect, I would have been tempted to practice it myself. As you know, I have devoted my life to studying poison techniques, and this martial art is practically tailor-made for me."

Su Xin continued reading, growing increasingly shocked.

The Five Poisons Mixed Method is extremely potent, as the five poisons have conflicting and mixed properties, and once an enemy is poisoned, it is a fatal disaster.

The book clearly states: If the poison is misdiagnosed, administering medicine to counteract the cold poison will ignite the fire poison in the body, causing the poisoned person to be instantly burned by intense fire.

If medicine to expel fire poison is used first, it will exacerbate the spread of bone-rotting poison, causing the poisoned person's bones to break and die in agony.

Unless one possesses unparalleled medical skills, capable of accurately identifying the five toxins and detoxifying them step by step in a specific order, those poisoned will die instantly, with no cure.

Of course, as a cultivator, Su Xin was able to control the five toxins in his body and naturally detoxify himself, so he didn't need to worry about being harmed by his own poison skills.

Su Xin was so engrossed in watching that when he looked up, Wang Nangu had already vanished.

It seems she couldn't wait to go and show off to Hu Qingniu.

After all, she had researched and developed the Five Poisons Mixed Yuan Technique, and she was determined to show off her skills in front of Hu Qingniu. She wanted to see what this "Medical Immortal" had to say.
